A simple copper/aluminum hydrotalcite (Cu/Al-HT) catalyzed arylation of phenols with aryl iodides afforded the corresponding diaryl ethers in moderate to excellent yields. This ligand- free Cu/Al-HT catalyzed coupling of aryl iodides with phenols resulted in high yields of diaryl ethers in the absence of an additive. The catalyst was quantitatively recovered from the reaction by simple filtration and reused for a number of cycles. Georg Thieme Verlag Stuttgart New York.

Employing KF/Clinoptilolite as an efficient base the cross-coupling reactions of various phenols with aryl iodides could be successfully carried out in the presence of copper oxide nanoparticles. The C-O coupling products were obtained in moderate to good yields (62-87%) for a variety of substrates. The Royal Society of Chemistry and the Centre National de la Recherche Scientifique 2014.

Copper(II) trans-bis-(glycinato) complex, easily prepared by the solid state reaction of copper(II) acetate and glycine (trans-[Cu(glyo) 2·H2O]) was found to be an efficient, recyclable, and high yielding catalyst for the Ullmann type synthesis of diaryl ethers via the cross coupling of phenols with aryl halides without using any additives at relatively low reaction temperature. The catalyst could easily be recovered by simple filtration and was reused for several runs with consistent catalytic activity.
